Letters Patent No. 89,575, dated May 4, 1869.

IMPROVEMENT IN WRENCHES.

The Schedule :eier-red to in these Letters Patent and making part pf the same.

To all 'whom it may concern:

Be it known that I, JOHN GOODIN, Iof Centrala, in the county of. Marion, and in the State of Illinois,

have invented certain new and useful Improvements in Wrenches; and do hereby declare that the following is a full, clear, and exact description thereof, reference'being had to the accompanying drawings, and

to the letters of reference marked thereon.

p a. part of this specification, and in which- Figure 1 is a side view of the wrench;

Figure 2, au edge view of the same; n

Figure 3, a side view of the movable jaw; and

Figure 4, a sideview of the stationary jaw.

A represents the handle of the wrench, which at one end is'cut and bevelled, so that nails can be drawn with the same. Y

At the other end the handle A spreads, forming the flat, broad portion B, at the end of which, on oneside, the stationary jaw O is formed. K s

On the same side as Ithe jaw G, but near the base of the dat portion B, is a raised surface, a, on which a dog, b, is pivoted, the inner end of said dog, or pawl being pressed inward by a spring, c, secured to a ange, d, rising from near the base of the at portion B.

Along the opposite side of the tlat portion B, is a raised flange, e, the object of which will he hereinafter set forth.

Across .the flat portion B, between the raised surface a and the ilange e, is an elongated slot, f, rounded at both ends, as shown in fig. 4.

The under side of the fiat portion B is grooved to receive the slide D, at one end of which is formed the jaw E.

The groove on tbe under side of the dat portion B extending across the same, enables the slide D to be moved from one side to the other, thus causing the vmovable jaw E to separate from or approach to the stationary jawG on a line at rightangles with the handlev A, instead of parallel, as is usually the case.-

A cam-wheel, F, which is provided on one side with notches t' i, is pivoted by means of a screw, G, which passes through the' slot fin the ila-t portion B, and into the slide D, thus atthe Sametime holding said slide in its position in the vgroove on the under side.

By turning *the eam-wheelF, its outer edge presses against the iiange e, which causes the slide D, 'jaw E, and the cam-wheel also t0 move closer to the stationary jaw C, and the dog, or pawl b being pressed against, .or in the notches 'i fi, holds the movable jaw in any position desired.

To separate the jaws, it is only necessary to raise the'pawl d out of the notch, whenthe cam-wheel can be turned in the opposite direction, which causes the slideGD and -jaw E to move away from the stationary `)aw Having thus fully described my invention,

What I .claim as new, and desire to secure by Letters Patent, is 2 1. The arrangement of the handle A, having a flat, broad portion, B, whch issiotted and grooved as described, the stationary. jaw C, raised surface a., pawl b, spring c, and iianges d ande, all substantially as shown and described.

2. In combination with the `handle A, flat portion B, and stationary jaw C, the slide D, movable jaw E, and notched cam-wheel F, all constructed and operating substantially as and for the purposes herein set forth.

In testimony that I claim the foregoing, I have hereunto set my hand, this 1st day of February, 1869.

JOHN GOODIN.
